Aero Engine Holes Drilled Fast with EDM
R
equirements for fast precise drilling of cooling air holes and shaped diffuser holes in blade and vane segments for aerospace applications have grown substantially due to new engine programs that emphasize improved engine perfor- mance and reduced fuel consumption. Always a challenge, producing the wide range of hole shapes and sizes within a single setup is highly desirable to reduce the variety and num- ber of tools required, as well as overall cycle times. The new EDBV3 Fast Hole Drill EDM from Makino (Auburn Hills, MI) builds on Makino’s proven EDM platforms with onboard filtration and resin systems and a user-friendly control system featuring prepro- grammed hole profiles. The two-axis rotary table in combination with auto- matic tool change (ATC) and automatic guide change (AGC) systems enables manufacturers to machine complex fea- tures untended, saving time and money without the risk of losing part quality or accuracy.
All EDM drilling with the EDBV3 is performed fully submerged under water for higher part quality, improved stabil- ity, and up to ten times faster processing speeds than conventional technologies. To further improve productivity, the EDBV3 uses a single-electrode process- ing approach, which avoids the high cost of custom multi-electrode holders and standardizes the tool holders with a flexible and cost-efficient system. To prevent back-wall impingement during blade and vane cavity wall pen- etration, the EDBV3 includes a propri- etary sensitive breakthrough detection
